AXLEI-BEARING.

Specification of Letters Patent.

Patented July 2, 1.907.

lApplieationiiled December 19,1906. Serial No. 348,611.

` ticularly applicable to bearings used on the axles of vehicles, although itis capable of other uses or in connec tion with other journals as desired. v

The object of the invention is to provide improved means for carrying and spacing a series of rollers which are located between the axle and the box, said rollers being carried 'so that they are held against displacement and retained in proper position.

An especial feature is that the rollers are so held that they will not fall out or oi'f when the box is removed, as in the act oi removing the wheel from the axle. This is particularly advantageous in connection with vehicle wheels which have to be frequently removed for oiling or other purposes. The rollers are so held, nevertheless, that they can be readily removed or lreplaced by being pulled out endwise from the retaining and spacing device.

The invention is illustrated in l.the accompanying drawings, in which y Figure lis a side elevation of the bearing, with the box removed. Fig. `2 is a central longitudinal section. Fig. 3 is a cross section on the line 3 3 of Fig. 2.

'Referring specificallyto the drawings, the axle is indicated at 6 and the box at 7. The ormeris reduced for' about half the length of the bearing, forming a shoulder as at 8, and it is threaded at the end to receive the nut 9 which holds the parts and which also holds the rollers in place lengthwise.

.The rollers Al0 are of substantially the same length as the bearing and are arranged ina circular series around the axle, being held againstglengthwise movement by the shoulder 1l at the heel oi the axle and the nut 9 as stated. They are retained and spaced byv a ring l2 which lits loosely upon the reducedportion of the axle, against the shoulder' 8. The rollers extend through notches 13 in the periphery of the ring. The notches are undercut or comprise more than a half circle, so that .when the rollers are inserted therein by endwise moveaxle sh with the bearing surface inside the shoulder 8,

a sleeve 14 is slipped on the reduced portion oi the axle between the nut and the ring 12. The sleeve ts at a sling t and its thickness is equal to the depth of the shoulder 8,'so-vthat a fiushbearing surface is formed for both ends of the rollers 10.

The ring l2 is quite loose upon the axle, so that there is little or. no friction between th'e inside of the `ring and the surface oi the axle. Furthermore, the notches 13 in the ring are of such depth that they extend below the bearing surface of thel axle, and consequently the series of rollers rest upon the bearing surface of the axlerather than upon the bottom ofthe notches. The outer sides of the rollers project beyond the circumference of the ring 12, in Contact with the box, so that the rollers are held between the bearing surface of the axle and box,

respectively, and are Amerely retained and spaced by' the ring 12.

As stated, the rollers will not dropout when the box is removed ,i but they may be removed or replaced when I claim:

' thereof and applying the ring, sleeve and rollers thereto.

1. The combination with a box, and an axle having :i

reduced portion, of a series of rollers between the box and axle, a spacing ringy onthe reduced portion of the axle and having notches through which the rollers extend, and

'a ysleeve on `the reduced portion of the axle, the surface of the sleeve being iush with the surface of the larger portion of the axle. A i

The combination with an axle having :i reduced portion, a sleeve on the axle, withA its outer surface flush with that of the larger portionl of the axle, a spacingrng on 3. The combination with an axle having a reduced portion about the middle of the. journal thereof, a ring fitting in said portion and extending around the axle and having undercut grooves across the periphery thereof, a box, and rollers extending through'said grooves and retained therein .against lateral removal, and bearingbetween the bore-and the axle. y

4. The combination with an axle having a reduced p`ortion about the middle of the journal thereof, a ring extendingaround said portion and having undercut grooves in the periphery thereof, s box, rollers between the box and axle'and extending through thegrooves and remov" able endwise therefrom, lthere-being a retaining shoulder extending around the axle at the lnnerend of the rollers, and a nut on vthe axle opposite the other end of therollers and the end of the box.
